Lead(II) sulfide is a black solid. It does not react with acids. However, if you heat it in the air, it will react. This reaction creates lead(II) oxide.
Even though it contains lead, lead(II) sulfide is one of the less harmful forms of lead. But remember, it is still important to handle it with care. All lead compounds should be treated carefully.
This compound is also used in a special test. It helps to find hydrogen sulfide gas. If you pass hydrogen sulfide gas over paper soaked in lead(II) acetate, the paper turns black. This happens because lead(II) sulfide is formed.
How is it Made?
You can make lead(II) sulfide by mixing two chemicals. One is hydrogen sulfide gas. The other can be lead(II) acetate or lead(II) nitrate. When these react, they form a black solid, which is lead(II) sulfide.
Where is it Found?
Lead(II) sulfide is found naturally as a mineral called galena. Galena often looks a bit shiny. It is the main source of lead metal.
What is it Used For?
Long ago, people used lead(II) sulfide as a black coloring. Today, its main use is in special devices. It is used in infrared detectors. These detectors can "see" heat, which is a type of infrared light.
